After a couple years of using the progasm I must say my outlook on what an orgasm is has been changed forever. I too was one of those guys who thought that all you had to do was insert, squeeze, and cum for an hour. I know now if you do not listen to your body you will just end up with a something stuck up your ass. My session today was the most amazing yet. After about 20 minutes of relaxation and gentle held contractions I noticed I could feel my pulse up against my progasm so I honed in on this and held a light inner contraction. Then it just exploded into a crazy calm sublime orgasm that peaked more than 5 times. Looked over at the clock and realized I had just cum for an hour. So don't get discouraged use your own bodys movements to get you there.
I know exactly that feeling. I get it when I'm highly aroused. My heart starts pumping and then I feel it on the perineum and it causes me to become erect, makes me shake and want to moan!
Great advice, rem!
